A rotary drive device in a mobile body includes a main wheel and a pair of drive assemblies opposing each other and each driving the main wheel. The main wheel includes driven rollers. One of the pair of drive assemblies includes a motor, a motor case, a drive force transmission, and driving rollers. The driving rollers are in the drive force transmission along a circumferential direction, and contact at least a portion of the driven rollers from one side of the rotary drive device of the axial direction. The drive force transmission rotates to transmit a drive force of the motor to the main wheel via the driving rollers. At least a portion of the motor case opposes at least a portion of the driving rollers in the axial direction.

It is an object to provide is an overcurrent relay having less number of parts and a smaller space to implement an automatic reset function and a manual reset function. A contact point mechanismincludes a movable contactor supportfor supporting a movable contactor composing a part of the usually-closed contact point while being maintained in the movable iron core, and a reset bararranged in a manner that is switchable between an automatic reset setting and a manual reset setting. The reset bardoes not engage with the movable contactor supportin an operation range of the movable contactor supportin the automatic reset setting. In addition, the reset barengages with the movable contactor supportin interlock with the movable iron coreto interrupt the reset operation of the movable iron coreof the electromagnetin the manual reset setting, and, when the reset operation is manually performed, engages with the movable contactor supportto be moved up to a position at which the reset operation is completed.
